BAC855 Upgrade Kit - Super73 ZX
This is the “OEM+” plug-and-play upgrade kit for your ebike (see FAQ for supported vehicles).
The HANDLWORKS system plugs into your stock vehicle, and includes a controller with harness, and display. By installing this controller and removing your stock programming, you can take control of your vehicle’s upgrade path - all programmability and upgrades are open to you.
Controllers come pre-flashed with a base tune that gives you a bump in performance (see Dyno Data for details). Throttle, PAS, and lights are all supported options.
Flash files are being developed to accommodate an upgrade track (different voltage, power, etc.). These will be flashable to your BAC system and available as you upgrade your vehicle.
Also introducing: our LIGHTS MODULE! We’re able to upfit the BAC855 with a custom converter to support all lights and peripherals. Check out the FAQ to learn more.

Does a non-Light Module kit work on my bike with lights?
Yes - it will work for the same powertrain, just without support for your stock lights. We have many customers who are purchasing the BAC855 kit without a Light Module because they have upgraded their lighting system already. If you have externally powered lights or your own DC/DC converter, you don’t need a Light Module and can purchase the non-LM kit for your vehicle.How does the Light Module work?
The Light Module (LM) is a custom-designed PCB add-on that contains all the step-down functions, along with switching circuitry to support peripherals such as lights and horns. We wire each (LM) to connect to the stock vehicle lighting, so a LM only supports the same lights as a stock vehicle. Hold the (+) button to turn on the LM.When does my order ship?
We are building-to-order with a lead time of 2-8 weeks, depending on where you land in each release.What is the performance upgrade from this kit?
See our dyno comparison page for detailed info.What are the ride modes?
Ride modes follow the legal US limits, with an unlimited mode at the highest. Your kit will power on at Mode 1 always.

Mode 2: 1200W, 28mph top speed (Class 3 ebike)

Certainly.Can I upgrade other parts?
Yes - contact us to discuss the upgrade paths. Generally, you just need to connect a new battery to the BAC855 system with an adapter cable, and flash the new firmware.What is your returns/warranty policy?
